Chapter-6|Electromagnetic Induction (EMI)| NCERT 12th Physics:
Motional Electromotive Force and Faraday’s Law:
Let a uniform magnetic field B is confined to the region ABCD and a coil PQRS is placed inside the magnetic field. At any instant t, the part P´Q= S´R=y of the coil is inside the magnetic field. Let l be the length of the arm of the coil.
Where, v is the velocity with which coil is pulled out of the magnetic field.
If e is the induced EMF, then according to Faraday’s law
